Nome Tatsunagi

Nome Tatsunagi is a character in Cardfight!! Vanguard G: NEXT. He is the older brother of Takuto Tatsunagi, as well as the newest head of the Tatsunagi Foundation. Nome's role is merely to observe the interactions between Planet Cray and Earth, claiming absolute neutrality, something he takes more seriously than his younger brother Takuto Tatsunagi. Like his brother, he has a slight whimsicality to his calm disposition.
